When you flip a switch or press a button two metal contacts come together. It might seem like they make immediate contact and complete a circuit. However, in reality as they make contact they mechanically bounce, making brief contact several times before making a solid connection. In some cases this bounce can also be electrical […]
Switches are literally everywhere! They are in many of the devices we use on a daily basis and a most basic part of just about every electronics project! So in this electronics basics tutorial we’re going to cover the different types of switches and what the applications that they are used for. At its most […]
Batteries are everywhere in our lives. Not only in the products we buy, but in our electronics projects! It’s not always clear when we should use which time, or what even makes one type of battery different from another. In this tutorial we’re going to cover the different types of batteries and talk about some […]
In this tutorial, we’re going to learn how rotary encoders work! Rotary encoders (also shaft encoders) are a fantastic way to dial in a position, or determine the position of a shaft. This could be the position of a knob you are turning, or it could be an encoder connected to a stepper motor to […]
Ads: who needs ’em? Well, this website needs them to keep the lights on. But you don’t need them, right? That’s why ad blockers, usually in the form of browser extensions, are so popular. The problem with browser extensions, though, is that they only work with certain browsers or on certain devices. What if you […]
In this tutorial, it’s going to be all about rectifiers! We’re going to learn the basics of their operation, and then we’re going to build a bridge rectifier circuit out of four diodes that can be used in your projects to convert AC to DC. In a previous tutorial we talked about diodes and how […]
Oscilloscopes are super handy tools to have around the workshop. With an oscilloscope you can test electronics and devices to see if they are functioning correctly, and make repairs. In this article and video, we’re going to do a basics 101 oscilloscope tutorial and learn how they work! Watch The Oscilloscope Tutorial Video Let’s start […]
In this tutorial, we’re going to answer your burning question: “What is a capacitor?”! Capacitors are one of the most basic components used in electronics and most all of our projects incorporate a capacitor in some form or another. Understanding how they work and how to use them is a skill most beginners should learn. […]
In this tutorial we’re going to answer the fundamental question that you’ve all been asking recently, “What is a diode?” A diode is a fundamental component that is at the very basics of many electronics projects. Unlike some of the passive components we’ve talked about recently (like resistors), a diode is a semiconductor. And as […]
In this tutorial we learn how to do do an Arduino Celsius to Fahrenheit conversion (and Fahrenheit to Celsius too!). It’s a pretty simple operation and one that is asked quite often in the forums. Understanding the Difference Between Celsius and Fahrenheit So before we learn how to do an Arduino Celsius to Fahrenheit conversion, […]
